Subject: [PATCH v3 0/7] thermal: processor_thermal: Suport workload hint

Add support for Meteor Lake workload hints. Before adding this support,
some reorganization and clean up is required.
First four changes are for clean up and to reorganize code to add
support for workload hint. The last patch adds a test program as part
of self tests.

v3:
Changes in the commit log
Rename of files for using WT instead of WLT
Address comments from Rafael on v2

v2:
Changes in comments and commit log
Self test program is improved to disable workloadtype notification
on exit

Srinivas Pandruvada (7):
  thermal: int340x: processor_thermal: Move mailbox code to common
    module
  thermal: int340x: processor_thermal: Add interrupt configuration
  thermal: int340x: processor_thermal: Use non MSI interrupts by default
  thermal/drivers/int340x: Remove PROC_THERMAL_FEATURE_WLT_REQ for
    Meteor Lake
  thermal: int340x: processor_thermal: Add workload type hint interface
